Chinese medicinal herb for improving male ratio of fries of Sarotherodon sp

Abstract

The invention discloses a Chinese medicinal herb for improving the male ratio of fries of Sarotherodon sp. The Chinese medicinal herb is characterized by comprising the following components: 10.00 percent of longspur epimedium, 13.00 percent of eucommia bark, 9.00 percent of Codonopsis pilosula, 12.00 percent of licorice root, 18.00 percent of astragalus, 10.00 percent of medlar, 15.00 percent of motherwort herb, 12.00 percent of black soybean, and 1.00 percent of south dodder seed. By feeding a commercial feed containing the Chinese medicinal herb preparation for a long time, the secretion level of sex hormones of the Sarotherodon sp can be better promoted, and the male ratio of the fries can be improved; and the effect is close to the treatment effect of synthetic hormones. Moreover, the Chinese medicinal herb is a nuisanceless and low-residue ecological preparation, and the residue is difficult to form in fish bodies; the method has no adverse effect on the palatability of feeds, and has smaller irritation to fishes compared with the injection of the synthetic hormones; meanwhile, the raw material source of the Chinese medicinal herb is stable, the cost is low, and the production process is simple.

Description

technical field [0001] The invention relates to a Chinese herbal medicine for improving the male rate of tilapia fry. Background technique [0002] Tilapia has delicious meat, no intermuscular spines, wide appetite, moderate price, strong adaptability and disease resistance, and is popular among domestic and foreign consumers. In order to improve the economic benefits of tilapia aquaculture, the current aquaculture industry often adopts the high male tilapia breeding technology. In order to meet the needs of the tilapia farming industry, the hybridization technology is used for Kaohsiung one tilapia seed production At the same time, the industry also uses synthetic hormones such as estradiol to treat and induce fry to increase the male rate of fry. When artificial hormone induces fry, it is easy to form residues in the fish body, making the fish species not comply with the relevant regulations on the quality of fishery products at home and abroad, thereby affecting the expo...
